Enhancing And Evaluating Scientific Argumentation In The Inquiry-Oriented College Chemistry Classroom, Annabel D'Souza

Dissertations, Theses, and Capstone Projects

The research presented in chapters 2, 3, and 4 in this dissertation uses a sociocultural and sociohistorical lens, particularly around power, authority of knowledge and identity formation, to investigate the complexity of engaging in, supporting, and evaluating high-quality argumentation within a college biochemistry inquiry-oriented classroom.

Argumentation skills are essential to college and career (National Research Council, 2010) and for a democratic citizenry. It is central to science teaching and learning (Osborne et al., 2004a) and can deepen content knowledge (Jiménez-Aleixandre et al., 2000; Jiménez-Aleixandre & Pereiro-Munhoz, 2002). When students have opportunities to make claims and support it with evidence and …

Persistence In Stem: Development Of A Persistence Model Integrating Self-Efficacy, Outcome Expectations And Performance In Chemistry Gateway Courses, Shalini Srinivasan

Theses and Dissertations

STEM persistence has been an important issue, especially in the context of underrepresented groups based on race and gender. Researchers in the last decade or so have been examining the powerful impact that affective and cognitive factors can exert individually on performance and persistence. It is only reasonable to hypothesize that combining affective and cognitive measures would offer a more thorough understanding of factors that impact students’ performance and STEM persistence. Evaluating these outcomes in the context of gateway courses is particularly essential due to the non-negligible percentage of students who drop out of these courses or decide to change …

A Comparative Study Teaching Chemistry Using The 5e Learning Cycle And Traditional Teaching With A Large English Language Learner Population In A Middle School Setting, Cynthia Nicole Mcwright

Dissertations

For decades science educators and educational institutions have been concerned with the status of science content being taught in K-12 schools and the delivery of the content. Thus, educational reformers in the United States continue to strive to solve the problem on how to best teach science for optimal success in learning. The constructivist movement has been at the forefront of this effort. With mandatory testing nationwide and an increase in science, technology, engineering, and mathematics (STEM) jobs with little workforce to fulfill these needs, the question of what to teach and how to teach science remains a concern among …

Spatial Reasoning And Understanding The Particulate Nature Of Matter: A Middle School Perspective, Merryn L. Cole

Theses and Dissertations--Education Sciences

This dissertation employed a mixed-methods approach to examine the relationship between spatial reasoning ability and understanding of chemistry content for both middle school students and their science teachers. Spatial reasoning has been linked to success in learning STEM subjects (Wai, Lubinski, & Benbow, 2009). Previous studies have shown a correlation between understanding of chemistry content and spatial reasoning ability (e.g., Pribyl & Bodner, 1987; Wu & Shah, 2003: Stieff, 2013), raising the importance of developing the spatial reasoning ability of both teachers and students.

Few studies examine middle school students’ or in-service middle school teachers’ understanding of chemistry concepts or …
